Atomic‐Scale Light Coupling Control in Ultrathin Photonic Membranes

Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.
Ultrathin photonic nanomembranes provide atomic‐scale control over the coupling between incident light and high‐Q photonic modes, enabling angstrom‐level resonance tuning and strong field confinement. When integrated with TMD monolayers, they further yield enhanced light–matter interactions, offering a versatile platform for advancing quantum photonics,

Influência do tipo de amostragem na constante dielétrica do solo e na calibração de sondas de TDR Influence of sampling type on the dielectric constant and calibration of TDR probes

Revista Brasileira de Ciência do Solo, 2010
A técnica da TDR é uma importante ferramenta para o estudo do teor de água no solo. Para o correto emprego dessa técnica, é necessário calibrar modelos que relacionam o conteúdo volumétrico de água no solo com a constante dielétrica deste, considerando ...

Reengineering the Baldree Traffic Simulator for turfgrass wear and traffic research

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Historically, turfgrass researchers utilized the Baldree Traffic Simulator (BTS) to imitate foot traffic for the evaluation of athletic field wear tolerance and performance. Research was conducted to reengineer the BTS “feet” to improve adaptability and compatibility with other aerification units and determine biophysical effects on two native

Variation in Climate Shapes Seedling Recruitment Along Resource Gradients in a Northern Hardwood Forest

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Seedling counts over 26 years revealed that wetter‐site temperate tree species struggle to recruit in warmer, drier years, whereas drier‐site species are more climate‐tolerant. Shadier forests buffered seedlings from heat and drought. Local soils and canopy cover strongly shaped outcomes, revealing considerable differences among species in climate ...

Using time domain reflectometry in triaxial testing

, 2000
: Time domain reflectometry (TDR) can be used to determine the volumetric water content of soils. This note describes the utilization of a TDR miniprobe in triaxial testing. The TDR performance was examined with a series of tests that not only proved its

Embodied Intelligence for Soil Health toward Sustainable Smart Agriculture: Sensing the Soil with Flexible Geotextiles Sensors

Global Challenges, Volume 10, Issue 6, June 2026.
This review examines the transition from rigid to flexible soil sensing technologies in the context of soil as a dynamic and heterogeneous environment. By integrating sensor types, sensing modalities, materials, fabrication and deployment strategies, and IoT‐enabled energy and communication approaches, it highlights geotextiles as scalable sensing ...

Simulation of Soil Water Content in Clayey Soils Where Dissolution and Precipitation of Pedogenic Carbonates Impact the Accuracy of Sensors Measuring Soil Water Content

Hydrological Processes, Volume 40, Issue 6, June 2026.
This study deals with limitations of frequency domain reflectometry sensors, including data drift, when monitoring clayey soils with pedogenic carbonates. Despite these inaccuracies, the results demonstrate that corrected measurements of soil water content can still successfully calibrate hydrological models.
